Get Disconnected from the Server

The story is that I get disconnected from the Jabberd server once I either add or delete contact in the Roster.

Here is the just the piece of code::::

System.out.println("----

");

con = new XMPPConnection(host,port);

PacketFilter filter = new PacketTypeFilter(Message.class);

con.login(username, password);

con.addPacketListener(this,filter);

r=con.getRoster();

r.addRosterListener(this);

r.setSubscriptionMode(Roster.SUBCRIPTION_ACCEPT_ALL);

  1. r.createEntry(contact*"@"*host, null, null);

if( con.isConnected() ){

System.out.println(“Connected”);

}

else{

System.out.println(“Disconnected”);

  1. r.createEntry(“sohail@”+host, null, null);

Now what happens is that (1)contact is added successfully but the client gets disconnected immeditaly

{Disconnected is printed on the screen}

and so the exception is thrown when try to create new entry(2)… Not connected to server Exception

Kindly figure it out why is it so

Two things to try:

  1. I’‘m not sure you’'re allowed to use null for the nickname when creating a roster entry.

  2. Try adding a connection listener and then print the exception that is disconnecting you from the server.

Ok !!!

First of all let me tell you that i am trying to develop a GUI based application in java for which i am asking you guy for assistance. When the gui is initilzed i have crated the connection & relevent stuff as mentioned before.

Now what happen is that when I press add button on my gui it ask me to add new contact/friends information. it adds the contact information in the roster successfully but gets disconnected.

and now when i again try to add or delete contact while selecting from the list it throws java.lang.IllegalStateException: Not connected to server…

Dont you think its a wired kind of problem,

I have tried both stuff i.e added a connection listener but it is never called.I have also given nickname instead of null while adding a new contact.

What I have noticed …Enabling the debug mode, I observered that somewhat error type occurs have 404 code.

That is all I could say for now.

Ok thanks for the assiastance.

The xml send to the server is

The xml received from the server is

<iq xmlns=’‘jabber:client’’ id=’‘77WP2-39’’ type=’‘result’’/>

<presence xmlns=’‘jabber:client’’ from=’‘amina@aquarious.imaxan.ie’’ to=’‘sohail3@aquarious.imaxan.ie/Smack’’ type=’‘error’’>

<error type=’‘cancel’’ code=’‘404’’>

<item-not-found xmlns=’‘urn:ietf:params:xml:ns:xmpp-stanzas’’/>

After analyzizing I can easily conclude what was the problem…

Ok let me summarize it

First of all I had been adding contacts in the roster that were never registered in the server. In other words dummy entries…

And finally when i tried to remove those dummy entries, at first I could remove it but it get disconnected i.e stream is closed

Now tell me that while adding new entries in the roster, how can we make a check that it not a dummy entry i.e the user is registered in jabberd Server…

I think you got my point ! !
